Presence of cardiac pacemaker

This code indicates that a patient has a cardiac pacemaker implanted. This device is used to regulate the heart's rhythm, typically for conditions like bradycardia or heart block. It does not specify the type of pacemaker or the reason for its implantation.

Use this code when documenting the long-term presence of a cardiac pacemaker in a patient's medical history. It is appropriate for follow-up visits, medication management, or when the pacemaker is an incidental finding during treatment for other conditions. Do not use for initial implantation or device management.

• Do not use this code if the encounter is for the adjustment or management of the pacemaker; refer to codes in category Z45.0-.
• Distinguish from Z95.810, which is specifically for an automatic implantable cardiac defibrillator with a synchronous pacemaker.
• This code is typically a secondary diagnosis, indicating a pre-existing condition, unless the reason for the encounter is directly related to the presence of the device (e.g., routine check-up where no adjustment is made).
